OBJECTIVES The primary objective was to identify the number of residency projects presented at the Pediatric Pharmacy Association (PPA) Bruce Parks Memorial Residency Showcase that were subsequently published. Secondary objectives included a comparison of subsequent publications after residency completion between those who did and did not publish their residency project and an analysis of factors associated with subsequent publications. METHODS This was a descriptive study including all pediatric-focused resident projects presented at the PPA Bruce Parks Memorial Residency Showcase from 2006 to 2015. Literature searches for all the pediatric-focused residency projects and any subsequent publications were performed. Data collection included residency type (i.e., postgraduate year 1 [PGY1], postgraduate year 2 [PGY2]), project category, and initial position after residency. A zero-inflated Poisson regression was used to analyze subsequent publication status while controlling for other factors. Statistical analyses were performed using SAS/STAT, with a priori p value < 0.05. RESULTS There were 434 projects presented by 401 residents. Seventy-four (17.1%) were published, with the majority being PGY2s (74.3%). Subsequent publications were identified for 162 residents (40.4%), with a higher percentage in those who published their pediatric-focused residency project versus those who did not, 59.5% versus 32.8%, p < 0.001. Factors associated with subsequent publications were those who published their residency project, initial position in academia, and PGY2s. CONCLUSIONS Of the residency projects presented at the showcase <20% were subsequently published. Those who published their residency research project were more likely to have subsequent publications. Future efforts should be taken to ensure that residents have the tools/confidence to independently publish their research/scholarship. [ABSTRACT FROM AUTHOR]

The association of disulfiram-like reaction with concomitant use of metronidazole and alcohol has been reported in the literature; however, alcohol containing oral liquids may not always be identified as a culprit. A case of a 14-year-old patient who experienced a possible disulfiram-like interaction while receiving metronidazole and Prednisone Intensol solution is reported. Metronidazole oral suspension was initiated for treatment of Clostridium difficile-associated diarrhea. Later, a 5-day course of oral Prednisone Intensol solution was initiated. On day 2 of concomitant metronidazole and steroid therapy, the patient experienced severe discomfort and abdominal distention accompanied by new onset tachycardia. A disulfiram-like reaction between the steroid solution and metronidazole was suspected; therefore, the Prednisone Intensol was discontinued. The patient's mother reported that, following discontinuation, the patient slept well for the first time in 2 days. Use of the Naranjo Adverse Drug Reaction Probability Scale indicated a possible relationship (score of 4) between the concomitant medication use and the gastrointestinal discomfort and tachycardia. If this interaction between metronidazole and alcohol containing medications occurs, it may be initially unrecognized, potentially resulting in patient discomfort or harm. It is important for healthcare professionals to identify these potential drug-drug interactions so that alternative medications may be utilized and offending agents can be avoided or replaced.

We sought to investigate whether magnesium oxide bound to soy protein (MGP) increases serum magnesium concentrations with less diarrhea compared to commonly prescribed magnesium salts. Subjects were switched to MGP at a near- equivalent daily elemental magnesium dose. Mean serum magnesium levels were compared. If magnesium levels remained <1.7 mg/dL after switching to MGP, subjects were enrolled into Part 2 and received a one-time MGP dose adjustment. The MGP daily dose was increased by 266 mg. For both parts 1 and 2, subjects recorded the number and quality of their stools to assess gastrointestinal (GI) tolerability of MGP. Twelve pediatric kidney transplant recipients completed Part 1. Mean serum magnesium levels increased from 1.61 (SD 0.1) on standard MG to 1.69 (SD 0.1); t(11) = 2.6, P = .02 on MGP. Five subjects completed Part 2, and all achieved serum magnesium ≥1.7 mg/dL (mean 1.75 mg/dL, SD 0.06; t(4) = 2.7, P = .06). Subjects reported the same number of, but looser bowel movements with MGP; however, individuals did not perceive intolerable GI symptoms with MGP therapy and all chose to remain on MGP at the end of the study. At an equivalent mg/kg/d dose of elemental magnesium, serum magnesium levels on MGP were significantly higher. [ABSTRACT FROM AUTHOR]

Study Objective To determine if significant correlations exist between glomerular filtration rate (GFR) prediction equation values, derived by using the original Schwartz equation and the Chronic Kidney Disease in Children (CKiD) bedside equation with a 24-hour urine creatinine clearance (Clcr) value normalized to a body surface area of 1.73 m2 in overweight and obese children. Design Prospective analysis (20 patients) and retrospective analysis (43 patients). Setting Pediatric inpatient ward and pediatric nephrology clinic at a comprehensive academic medical center. Patients Sixty-three pediatric patients (aged 5-17 years), of whom 27 were overweight (body mass index [BMI] at the 85th percentile or higher) and 36 were not overweight (BMI lower than the 85th percentile [controls]) between 2007 and 2012. Methods and Main Results Data from the overweight patients were compared with nonoverweight controls. GFR values were calculated by using the original Schwartz equation and the CKiD bedside equation. Each patient's 24-hour urine Clcr value normalized to a body surface area of 1.73 m2 served as the index value. A Pearson correlation coefficient model was used to determine association between the 24-hour urine Clcr value (index value) with the Schwartz and CKiD GFR estimations. Significant correlation was found to exist between the Schwartz and CKiD bedside GFR estimations relative to the 24-hour urine Clcr in the control subjects (r = 0.85, p<0.0001, and r = 0.85, p<0.0001, respectively). Significant correlation was also found to exist between the Schwartz and CKiD bedside GFR values with the 24-hour urine Clcr value in overweight subjects (r = 0.86, p<0.0001, and r = 0.86, p<0.0001, respectively). The Schwartz equation estimated average GFR 21.75 ml/minute/1.73 m2 higher than 24-hour urine Clcr (p<0.0001) in overweight children with a kidney disorder. The CKiD bedside GFR estimations were not significantly different compared with 24-hour urine Clcr values for the overweight group with kidney disorder (p=0.85). Conclusion The Schwartz and CKiD bedside estimations of GFR correlated with 24-hour urine Clcr values in both overweight and nonoverweight children. Compared with the Schwartz equation, which tended to overestimate renal function, the CKiD bedside equation appeared to approximate 24-hour urine Clcr more closely in overweight children with kidney disorder.

Intensive insulin management (IIM) in type 1 diabetes facilitates improved glycemic control and a reduction in long-term diabetes complications. We hypothesized that IIM can be started at diagnosis without deleterious effects on hemoglobin A1c (A1c), body mass index (BMI), and severe hypoglycemia regardless of payer source. Type 1 diabetes patients aged 0–18 yrs, in an academic endocrinology practice were identified for a retrospective chart review. Fifty-four patients on conventional insulin management (CIM) were compared to 51 on IIM. Insulin regimens, payer, and A1c values were compared at baseline, 12, 15, and 18 months. Secondary analyses included BMI changes and hypoglycemia frequency. Overall mean A1c values for the IIM group (8.15 ± 1.41) were lower across all time periods compared to the CIM group (8.57 ± 1.52). Repeated measuresanova revealed a significant treatment group effect ( p = 0.01) with no time effect ( p = 0.87) or interaction (group by time) effect ( p = 0.65). Private insurance patients had lower mean A1C values than Medicaid patients (χ2 = 4.5186, p < 0.05), regardless of regimen. A1c values between IIM and CIM were not statistically different within the Medicaid group. BMI changes between groups were not different. Chi-square analysis for severe hypoglycemia revealed no group differences. In conclusion, IIM had improved glycemic control. Private insurance vs. Medicaid patients had lower mean A1c values regardless of treatment group. Considering Medicaid patients only, IIM was not inferior, and for those with private insurance, IIM was superior. IIM, initiated at diagnosis, is a reasonable approach for newly diagnosed children with diabetes regardless of payer source. [ABSTRACT FROM AUTHOR]

Percy Medicine is a nonprescription gastrointestinal suspension containing bismuth subsalicylate as the active ingredient (1050 mg/10-ml dose). A 3-month-old infant with colic developed salicylate toxicity requiring hospitalization in the pediatric intensive care unit (PICU) as a result of continued administration of this medicine. Bismuth subsalicylate has an aspirin equivalency conversion factor of 0.479 (approximately half the strength of aspirin). For 3.5 weeks the infant's parents administered the medicine, which provided the equivalent of aspirin 57-84 mg/kg/day with no reported problems. However, on the day of admission the baby presented with central nervous system depression and respiratory distress. Assessment at a local emergency facility revealed metabolic acidosis; his serum salicylate concentration was 747 mg/L. After acute management, the patient was transferred to our hospital, where he was treated with whole bowel irrigation and alkalinization therapy. Subsequently, the baby required 4 days of management in the PICU and 2 additional days of observation in a general nursing unit before he was discharged home without incident. The parents had chosen Percy Medicine based on the picture of a baby on the front of the package and because of its placement on the shelf next to a drug their family physician had recommended previously. Salicylate-containing products are not routinely recommended for children aged 1 year or younger. The general public may assume that over-the-counter products are safe because they do not require a prescription. Health care professionals must be responsible for educating the public regarding risks associated with over-the-counter products and the need to read and follow label directions.

Autosomal-dominant polycystic kidney disease (ADPKD) is characterized by formation of cysts from tubular epithelial cells. Previous studies indicate that secretion of prosta-glandin E2 (PGE2) into cyst fluid and production of cAMP underlie cyst expansion. However, the mechanism by which PGE2 directly stimulates cAMP formation and modulates cystogenesis is still unclear, because the particular E-prostanoid (EP) receptor mediating the PGE2 effect has not been characterized. Our goal is to define the PGE2 receptor subtype involved in ADPKD. We used a three-dimensional cell-culture system of human epithelial cells from normal and ADPKD kidneys in primary cultures to demonstrate that PGE2 induces cyst formation. Biochemical evidence gathered by using real-time RT-PCR mRNA analysis and immunodetection indicate the presence of EP2 receptor in cystic epithelial cells in ADPKD kidney. Pharmacological evidence obtained by using PGE2-selective analogs further demonstrates that EP2 mediates cAMP formation and cystogenesis. Functional evidence for a role of EP2 receptor in mediating cAMP signaling was also provided by inhibiting EP2 receptor expression with transfection of small interfering RNA in cystic epithelial cells. Our results indicate that PGE2 produced in cyst fluid binds to adjacent EP2 receptors located on the apical side of cysts and stimulates EP2 receptor expression. PGE2 binding to EP2 receptor leads to cAMP signaling and cystogenesis by a mechanism that involves protection of cystic epithelial cells from apoptosis. The role of EP2 receptor in mediating the PGE2 effect on stimulating cyst formation may have direct pharmacological implications for the treatment of polycystic kidney disease.

Background: Few studies have compared clinical outcomes and medication use between obese and nonobese children in the pediatric intensive care unit (PICU). Objectives: The primary objective was to compare clinical outcomes including mortality, PICU length of stay (LOS), and mechanical ventilation (MV) requirement between obese and nonobese children. Secondary objectives included analysis of factors associated with these outcomes and medication use between groups. Methods: This retrospective study included children 2 to 17 years old admitted to the PICU over a 1-year time frame. Patients were categorized as obese, body mass index (BMI) ≥ 95th percentile, and nonobese (BMI < 95th percentile). Three binary regression models assessed the impact of obesity on clinical outcomes. Results : There were 834 admissions, with 22.1% involving obese children. There was no difference in mortality, MV requirement, or PICU LOS between groups. There were no associations with obesity and clinical outcomes found, but an association was noted for medication classes and receipt of continuous infusions on clinical outcomes. There was no difference noted in the median number (interquartile range [IQR]) of medications between obese and nonobese children, 8 (6-13) versus 9 (6-15), P =.38, but there was a difference in patients receiving a continuous infusion between obese and nonobese children, 24.4% versus 8.8%, P <.01. The 15 most used medications in both groups included analgesics, antimicrobials, corticosteroids, bronchodilators, and gastrointestinal agents. Conclusions : One-fifth of all admissions included obese children. Obesity was not associated with mortality, PICU LOS, and MV requirement, but the number of medication classes and continuous infusions were associated with these outcomes. [ABSTRACT FROM AUTHOR]

The article discusses a study which was conducted to evaluate bumetanide continuous-infusion dosing in critically ill pediatric patients. Descriptive and inferential statistics were used to interpret the results. The results indicated that the initial bumetanide continuous-infusion dosage was inversely related to the number of dose increases required. The study thus provided the evidence for selection of initial doses of bumetanide continuous infusion in children.
